Why does alum make big crystals?

It's not that only alum makes big crystals.. There are so many compounds that can make big crystals. Even Sodium Hydroxide makes very good and big crystals. For crystals you need a uniform arrangement of atoms in space. For big crystals all you need is patience. The slower is the crystallization process the bigger crystals are formed. What industries do is called seeding. They make a good concentrated solution of the compound whose crystals are needed and then they put a crystal of the same compound in the solution. The new crystals form and attach to the crystal making quick and big crystals.


What is the difference between homemade and store bought crystals?

Homemade crystals are typically made through a DIY process using household ingredients like sugar or salt, whereas store bought crystals are manufactured using specific materials and techniques for consistency and quality. Homemade crystals may vary in size, shape, and purity, while store bought crystals are often uniform in appearance and chemical composition due to controlled production processes. Additionally, store bought crystals may have higher purity levels and be more suitable for specific uses such as scientific experiments or crystal healing practices.


What do you see when distilled water is added to washing soda crystals?

When distilled water is added to washing soda crystals (sodium carbonate), it dissolves the crystals to form a clear, colorless solution. This happens because washing soda is water-soluble, meaning it can dissolve in water to form a homogeneous mixture.


Are iodine crystals homogeneous mixtures?

Iodine is an element, so a pure substance, not a mixture, (so even not homogeneous).


A mineral specimen has very small crystals what is the best explanation for how this happened?

The small crystals likely formed due to rapid cooling of the molten rock or solution from which the mineral precipitated. This rapid cooling did not allow enough time for the crystals to grow larger, resulting in the formation of small crystals.

Why can't you get swarovski crystals wet?

Swarovski crystals are made with a special coating that can be damaged or dulled when exposed to water or moisture. This can cause the crystal to lose its shine and brilliance. It is recommended to avoid getting Swarovski crystals wet to maintain their quality and appearance.


How much are purple crystals worth?

Depends on the particular purplish crystal. Amethyst is not too expensive but other purplish crystals expensive. So it depends.


Are there crystals on the moon?

it would be unlikely as there is nothing living there.


Why does igneous rock have bigger crystals and some have small crystals?

The reason why is because of where it comes from in a volcano and how fast it cools. If it cools slowly then it will have bigger crystals because the longer it has to cool the longer the crystals have to grow. So dose that answer your question


Do crystals melt on their own?

no i don't think so


What does the presence of large crystals tell you about the rocks' formation?

Larger crystals suggest slower formation. Crystals would have less time to grow if cooled quickly, and so would be smaller.
